FOUR-WHEEL DRIVE
OPERATION — IF EQUIPPED
Jeep Active Drive
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is automatic
with no driver inputs or additional driving skills
required. Under normal driving conditions, the
front wheels provide most of the traction. If the
front wheels begin to lose traction, power is
shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater
the power transfer to the rear wheels.
Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a pre-
emptive effort to improve vehicle launch and
performance characteristics.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the
power transfer unit.
Four Wheel Drive (4x4)
The four wheel drive (4WD) is fully automatic in
normal driving mode.
NOTE:
It is not possible to carry out the change of mode
when the vehicle exceeds the speed of 75 mph
(120 km/h).
Enabling Four Wheel Drive (4x4)
The buttons for the activation of four wheel drive
are located on the device Selec-Terrain and
allow you to select the following:
•
4WD LOCK
•
4WD LOW — (Trailhawk models only)
Active Drive Control — If Equipped
The Power Transfer Unit (PTU) is locked to
ensure immediate availability of torque to the
rear drive axles. This feature is selectable in
AUTO mode and automatic in the other driving
mode. 4WD LOCK can be enabled by the
following ways:
•
When the 4WD LOCK button is pushed.
•
When the Selec-Terrain switch is rotated from
AUTO to any other off-road modes.
Active Drive With Low Control — (Trailhawk
models only)
The 4WD LOW mode helps to improve the
off-road performance in all modes. To enable
4WD LOW, please follow the steps below:
Enabling 4WD LOW
With the vehicle stationary, the ignition in the
ON/RUN or with the engine running, shift the
transmission into NEUTRAL and push the but-
ton once 4WD LOW. The instrument cluster will
display the message
"
4WD LOW
"
once the shift
is complete.
NOTE:
•
Both LOCK and LOW LEDs will blink and
then become active on the Selec-Terrain
switch until the shift is complete.
•
The instrument cluster display will illuminate
the
"
4WD LOW
"
icon.
